Answer:

$-\frac{7}{8}a-\frac{1}{6}$ (the first box is 7/8 and the second box is 1/6)

Step-by-step explanation:

Step 1: Combine like terms.

$(-\frac{5}{8}a-\frac{1}{4}a)+(\frac{2}{3} -\frac{5}{6})$
$(-\frac{5}{8}a -\frac{2}{8}a)+(\frac{4}{6}-\frac{5}{6})$
$-\frac{7}{8}a-\frac{1}{6}$

Therefore, the answer is $-\frac{7}{8}a-\frac{1}{6}$ . (Again, the first box is 7/8 and the second box is 1/6).

At the beginning of an environmental study, a forest covered an area of 1500 km2 . Since then, this area has decreased by 9.8% e

fredd [130]

Answer:

$A(t)=(0.902)^t \cdot 1500$ $[km^2]$

Step-by-step explanation:

In this problem, the initial area of the forest at time t = 0 is

$A_0 = 1500 km^2$

After every year, the area of the forest decreases by 9.8%: this means that the area of the forest every year is (100%-9.8%=90.2%) of the area of the previous year.

So for instance, after 1 year, the area is

$A_1 = A_0 \cdot \frac{90.2}{100}=0.902 A_0$

After 2 years,

$A_2=0.902 A_1 = 0.902(0.902A_0)=(0.902)^2 A_0$

And so on. So, after t years, the area of the forest will be

$A(t)=(0.902)^t A_0$

And by substituting the value of A0, we can find an explicit expression:

$A(t)=(0.902)^t \cdot 1500$ $[km^2]$

So yeah can anyone help me out be a tone

Brut [27]

Answer:

p = -4

Step-by-step explanation:

-3( 2+4p) + 7 = 49

Subtract 7 from each side

-3( 2+4p) + 7 -7= 49-7

-3( 2+4p) = 42

Divide by -3

-3( 2+4p) /-3 = 42/-3

( 2+4p) = -14

Subtract 2 from each side

2+4p-2 = -14-2

4p = -16

Divide by 4

4p/4 = -16/4

p = -4
